+The Matrix Template Library is a C++ class library for basic linear
+algebra. The MTL is designed for high-performance while at the same
+time taking advantage of the generic programming paradigm (ala the
+STL) to allow much greater flexibility and breadth of
+functionality. Many new and advanced programming techniques were used
+in the construction of this library.
+
+The MTL is a low level library in the sense that the user must be
+conscious of the matrix type being used, and that all computationally
+expensive operations are explicit. The MTL is not a C++
+Matlab. Nevertheless, the interface is designed to be simple and easy
+to use.
+
+The matrix types provided include compressed sparse row/column,
+banded, packed, diagonal (and tridiagonal), envelope, array of
+pointers, and of course dense matrices. All matrix types share a
+common and easy to use interface.
+
+The algorithms consist of the traditional basic linear algebra
+routines (from the BLAS level-1 to 3) which includes matrix and vector
+arithmetic as well as operations such as backward substitution and
+norm calculations.
